FIRE-ESCAPE.

Application filed January 2, 1913.

To all whom it may concern:

Be it known that I, J OHN CoLmsoN BRO\VN, of the city of Niagara Falls, in the county of Welland, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Fire-Escapes, of which the following is the specification.

My invention relates to improvements in fire escapes and the object of the invention is to devise an appliance which may be readily placed in position in or removed from an upper story window of a building by firemen situated on the ground level of the building and by which people may be readily and safely lowered from such window and it consists essentially of a pole comprising a series of detachably connected lengths, and a supporting clutch mechanism at the top operated by a cord extending to the bottom of the pole, a suspending bracket supported by such clutch mechanism and designed to engage the window sill oir other suitable support and then to be freed from the clutch mechanism. a basket suspended from the bracket and means for lowering the basket either operated from the ground or by the occupants of the basket and means operated from the ground for removing the suspended bracket as hereinafter more particularly explained.

Figure l, is a front elevation of a portion of a building showing my device applied to a second story window. Fig. 2, is a vertical section through the building shown in Fig. 1 and showing my appliance attached to the window. Fig. 3, is an enlarged sectional detail of a window sill and my mechanism attached thereto. Fig. 4, is an enlarged perspective detail of the sus pension bracket and means for placing it in position in the window. Fig. 5, is an enlarged perspective detail of the suspension bracket.

In the drawings like letters of reference indicate corresponding parts in each figure.

A. is a portion of a building of which A is the second story window provided with a window sill A provided with the usual inner ledge A 13 is a suspension bracket comprising a vertical plate B designed, when in position, to rest against the front face of the window sill A B is a loop bar provided with a hooked end B having a point B 13 is a hinged plate pivoted at its lower Specification of Letters Patent.

end in the loop l3 swung in the bracket B secured to the plate B, The upper end of the plate B extends through the loop B and is provided with a curved portion B in which is formed a hole B.

B is a pulley block connected by a link B to the portion B by extending through the hole B.

C is a basket by which the occupants of the building may be lowered from an upper story window.

0 is a cross bar on which is swung the hook member C C is a cord connected at the lower end to the hook member C and extending over the pulley block B and down to the ground.

D is a pole provided at its upper end with the cross arm 1).

D is a pulley journaled in the outer end of the cross arm I) l) and D are vertical pulleys journaled at the front end of the cross arm D.

D and D are clutch members pivoted to the front end of the pole at D and D The clutch members D and D are spring held together by the tension spring D The clutch members D and D are provided with tail pieces D and D D is a cord secured to the tail pieces D and D from which it extends between the pulleys D and D and over the pulley D down to the ground.

E is a bracket secured to the front face of the pole D. The bracket is provided with a hooked outer end E and spring fingers E opposing the same. The pole D may be made in a plurality of links connected together by a clamping bracket.

When it is desired to place my apparatus in position. all that it is necessary to do is to connect the suspension bracket 13 to the clutch members D and D as shown in Fig. 4, the loop B thereof engaging between the hook E of the bracket E and the spring fingers E In this position the bracket B is raised to the window level and the hooked end passed through the window. If the window is closed the point end B of the bracket will serve to break the window. The hook B of the bracket will then engage with the window ledge A as shown in Figs. 2 and 8 and the cord D is then pulled by the firemen so as to throw the clutch members D and D in to the position shown in Fig. The members of the suspension bracket will then be freed from such clutch members and fall into the position shown in Fig. 3, the cord C of course, being attached to the bracket as shown in Fig. 3. The basket C may then be raised to the required height so that the people may escape out of the window.

For removing the suspension bracket B from the window so that it may be placed in another window in the building I pr0- vide the bracket F comprising the arms F and F having downwardly looped portions F and an upward extension F on which is journaled a spool F around which is wound the cord F having ahook F When it is desired to remove the bracket B the fireman takes the bracket F up to the window and places it over the sill with the loops F and F extending over the edge A as shown in Fig. 3. The hook is then passed through the eye D of the bracket B, the cord F extending over the edge of the window sill down to the ground.

G is a firemans hook connected to the pole G WfllCll is formed by a plurality of pole lengths connected together by the bracket G When removing the bracket B the hook of the pole G is placed on one of the arms of the bracket B and the cord F is pulled so as to throw the inner hook end of the bracket B out of engagement with the window ledge A and the bracket may then be removed through the window and lowered to the ground.

The connecting bracket G shown in Fig. 3 comprises two members G and G hinged together at G and designed to encircle two approaching ends of two adjacent pole lengths. The free sides of the members G and G are connected together by the swing hooks G engaging the projection G Al- 40 though I show this form of clamp, of course,

it will be understood that there are various forms which may be used which will accomplish the same result.

From this description it will be seen that I have devised a very simple device whereby a fire escape apparatus may be easily placed in an upper story window of a building by a fireman so that the people may be easily and quickly lowered therefroin' What I claim as my invention is:

1. A device of the kind described compris ing'a vertical plate, a looped bar, having one end terminating in a hook, a loop attached to said plate intermediate the ends thereof, a plate pivoted at its lower end in said loop and having its upper end extending through said looped bar, the upper end of said ver ticalplate being arranged to slide on said looped bar.

2. A device of the kind described comprising a vertical plate a looped bar attached to said plate terminating at one end in a hook portion, a second plate pivoted at its lower end to said first named plate said pivoted plate having its upper end extending through said looped bar.
